Shunt module targets electric power trains

Isabellenhütte’s IVT-S measurement system is a modular package designed for high dielectric strength in traction batteries and stationary energy storage devices.

The main focus is on achieving dielectric strength that is as high as possible for the intended application. High dielectric strength must be guaranteed in battery-powered vehicles, for example.

The IVT-S shunt-based measurement system has a maximum dielectric strength of 1000V. Its functional range includes the measurement of current and voltage in traction battery systems or stationary electrical energy storage devices. These systems, based on lithium-ion batteries, generate high energy density at which higher voltages can be applied with smaller currents. This is why the sensor’s dielectric strength also has to be correspondingly high − a key quality feature that distinguishes IVT-S. For fast-charging battery systems, this performance feature is extremely important.

Integrated in the IVT-S are a 16-bit analogue to digital converter and a CAN 2.0 interface. Firmware converts measurements charge and discharge data. In addition Isabellenhütte provides a CAN description file in *dbc format that helps IVT-S users to swiftly integrate the application.
